We discussed how oxidation & reduction are related to the Activity Series of Metals and used Standard Reduction Potentials to help determine whether single displacement reactions (anionic & cationic) would occur. Following some reinforcement examples, everyone had time then to work on finishing up the Lab 10 report and work on Labs 11 & 12 for tomorrow's deadline.
Unit test on Friday.
We reviewed the Net Ionic Equation practice questions that were assigned prior to break. Students then collected data for Lab 11 (Reactions between Ions in Solution) & Lab 12 (Investigating the Activity Series of Metals). Students mixed microscale quantities of solutions and observed whether or not a precipitate was formed (indicating a double displacement reaction had occurred forming a new substance). Students mixed samples of pure metals and solutions of their sulfates to observe which metal/solution combinations resulted in a reaction and which did not, in an effort to establish a ranking order of chemical activity (thus experimentally determining an activity series).
